A graphical programming environment using flowcharts.

Prerequisites

The following programs have to be available on the system for FlowTutor to be able to run:

• Python 3.9, 3.10, 3.11, 3.12
• For C programs only:
  • GCC - C-Compiler
  • GDB - Debugger

Documentation

An overview of FlowTutors functionality can be found in the projects Wiki

Running

FlowTutor is available through the Python Package Index:

python -m pip install flowtutor

Running C programs on macOS

Warning As of June 2023 there exists a bug in MacOS/GDB, that prevents the debugging functionality of FlowTutor from functioning correctly.

Flowtutor uses GDB for its C debugging functionality. Modern Darwin kernels (used in macOS) restrict the capability to assume control over another process, which GDB needs to debug the program. To give the correct permissions to GDB it needs to be code signed.

1. Create a certificate

Run the script macos-setup-codesign.sh from the gdb-codesign folder. This sets up a certificate in the System Keychain and trusts the certificate for code signing.

2. Sign and entitle the gdb binary

Execute the following command with gdb-entitlement.xml from the gdb-codesign folder:

codesign --entitlements gdb-entitlement.xml -fs gdb-cert $(which gdb)

3. Reboot

This refreshes the system's certificates and code-signing data.

Windows Installer Packages

The application is packaged with Pynsist for easier distribution on Windows.
